I configured multisite on an existing site which is on Linux Server. Now when, I try to create new site on the network, it's giving me fatal error: execution time exceeded 30 seconds. I increased it to 500 (5min) (in .htacess, yet it's giving me the same error, execution time exceeded 500s.
Why is it taking too much time to execute? How to solve the problem as increasing time limit is not helping in any case.
Note: I took backup of the same single site, and configured multisite on it using Localhost (wampp/windows). And it works perfectly fine there. No such issue occured.
